CENTRlFUGAL CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 628,725, dated July 11,1899.

Application filed February 25,1899- Serial No. 706,813. (No modelf:

To a/ZZ whom t may concern:

Beit known that I, ERIK GUSTAF N IcoLAUs SALENIUS, a subject of the Kingof Sweden and Norway, and a resident of Stora Kraftriket, Albano,Sweden, have invented certain Improvements in Centrifugal Separators, ofwhich the following is a specification.

This invention relates to the class of separators used for separatingcream from milk; and it has for its object to provide suchva separatorwith means for spreading and distributing the iniiowing liquid outwardlyover the internal inclined partitions therein, the latter being of aknown construction. These internal partitions are in the nature ofsuperposed inclined plates, and the main central tube of the drum is,for the purposes of this invention, flared or enlarged at its lower endand provided with distributing tubes or devices, which latterextendupward to the cover of the drum, above the inclined internalpartitions therein. The upper portions of these distributing devices areslotted or perforated, so that the milk rising therein can now outtherefrom onto said internal partitions, all as will be moreparticularly hereinafter described.

In the accompanying drawings, which illustrate an embodiment of theinvention, Figure l is a vertical axial section of the drum of theapparatus and its internal mechanism or devices. Fig. 2 is a plan of thebottom piece g in the drum on which the superposed internal partitionsare placed, the drum itself being seen in horizontal-section. Fig. 3 isa side elevation of the main central and distributing tubes detachedfrom the drum, the bottom piece g being seen in this View in verticalaxial section, taken at right angles to the section in Fig. 1. Fig. 4 isa plan view of the main central and distributing tubes detached. Fig. 5is a fragmentary vertical section, and Fig. 6 a horizontalsection,illnstrating a modified construction of the distributing device.

Referring primarily to Figs. 1 to 4, inclusive, lc is the drum proper, his the cover thereof, g is the bottom piece in the drum, and f are theinclined and superposed internal partitions in the drum between thecover h` and the bottom piece g. The cover h is de- 5o pressed orhollowed and shaped to fit onto the inclined partitions f, and it hasradial ribs to strengthen it. The cover is secured in place on the drumby means of a ring s and screws t. In general these features are alreadywell known.

The main central tube a, through which the liquid, as milk, is admittedto the drum, is flared or enlarged at its lower end b and provided atthis flared portion with suitable np- 6o right sockets c, in which areiitted upright distributing-tubes CZ, of which four are shown herein,Fig. 4. The sockets c are or may be integral with the flared Wall of theportion l), and they and the tubes cl open into the conical chamberWithin the portion h. The foot or lower end of the main central tube mayiit into a central opening in the base portion g of the bottom piece gor it may rest directly thereon, and at the top said tube is steadied 7oand held in position by the cover 7L, which has a short neckpiece it',embracing the reduced upper end of the central tube, above a shoulder h2on the latter.

It will be noted that the internal partitions f are roof-like orWedge-like and not conical, and that the cover 7L is of a correspondingshapeand fits down upon and over said partitions, as already stated'.The main central tube ct is provided exteriorly with radial 8o iiangesb', situated between the tubes d. These iianges project out about as faras the ilared base b of the central tube and extend up to and iit underthe cover h. The internal partitions f have central apertures of su- 8 5cient size to enable them to embrace the iianges b and tubes cl.

The tubes d have each a slot d in its outer face, extending from itsupper end down to about the level of the lowermost partition j' 9o ofthe series, or, in other Words,to about the level of the top of thebottom piece g.

The discharge-passages Z for the skimmed milk and the discharge-passagesm for the cream open out through the neck on the drum- 9 5 cover h, andthese outlets are controlled by a sleeve p, which is ported androtatable about said neck, being held in place by a screw-cap 2 iGeef/'c5 .betaken out together.

q on the upper end of said neck. The fixed pipe r for the admission ofthe milk extends down through an aperture in said cover and downthroughthe main central tube to near the bottom of the drum.

The milk descending through the tube i' into the chamber within theflared `portion or base .by Way of the discharge passage or passages m.

Apertnres e, Fig. 1, allow slime and other impurities fromrthe milk toescape from the chamber within the enlarged portion b of the centraltube out into the chamber g2 within the bottom piece g.

Vhen the internal devices of the drum are to be removed, thevcover h isrst taken off. The partitions flare'then taken out, and the vpartsincluding thel main central tube and the distributing-tubes (seen inFig. 4) can then This ability to remove allthe distributinginstrum entalities together possesses an important advantage over constructionswhere the distributing features are fixed separately in the drum. On theother hand, if a simple central tube only is employed, the partitions fdo not perform the ffull function required of them.

VThe modified construction illustrated in Figs. 5 and 6 differs fromthat already de'- scribed in the substitution for the slotteddistributing-tubes d of integral, hollow,.lateral, and radialenlargements a2 on the lower portion of the central tube d, as clearlyshown in Fig. 6. At their outer upright edges the enlargements a2 haveeach a series of apertures or perforations for the escape of the milk.These enlargements a2 may project far enough .to enter recesses formedin the inner edges of the partitionsf, as indicated in Fig.

6, where the inner circular margin of tlie parl titions is indicated bya dotted line. y Having thus described my invention, I claiml. In acentrifugal separator, the combination with the drum k, the bottom pieceg, the

depressed cover h, and the superposed partitions f, in the drum andembraced between the said bottom piece and cover, the latter parts beinginclined to it the partitions, of the main central tube a, having anenlarged lower end b`provided with a plurality ofconcentrically-arranged distributing devices, said devices beingsubstantially within the central apertures of the partitions f andupright, apertured faces adjacent to said partitions, substantially asset forth.

2. In a centrifugal separator, the combination with the drum, the bottompiece,and the superposed partit-ions in thedrum, of means fordistributing the milk over said partitions, said distributing meanscomprising a main, central tube enlarged rat its lower end and providedwith sockets c,and the upright tubes d in said sockets, said tubes beingconcentrically arrangedabout the central tube and having apertures intheir outerfaces for the escape of the milk7 substantially as set forth.

In a centrifugal separator,the combination with the drum 7a, thebottomvpiece g, the inclined ,superposed,and apertu red partitions f,andthe depressed cover h, saidbottom piece and cover being inclined to fitthemselves to the inclined surfaces of said partitions, of the maincentral tube a,having an enlargedflower portion b, and the uprightdistributing-tubes .as set forth.

In witness whereof I haverhereunto,signed my name in the presence of twosubscribing witnesses.
